April didn't just net the Seahawks 11 new players in the draft; Seattle also agreed to terms with nine undrafted free agents last weekend. They're guys who weren't taken in the draft for one reason or another -- often because of injuries -- but piqued Seattle's interest enough to bring them in for workouts and camp this summer.
''This was the hardest rookie free-agent period we've had,'' Seahawks GM John Schneider said Saturday after the NFL Draft wrapped up. ''Once you know that guys are making very hard decisions to come with you, that's when you know that you're improving.''
Why? Because free agents are less likely to join teams that are really good, since they'd have less of a chance to make the roster. The Seahawks were ranked No. 1 in ESPN's off-season power rankings, and this week retained the top spot in ESPN's post-draft poll.
Anyway, here are the nine (so far) free-agent rookies the Seahawks are bringing in this summer. Click through the gallery to meet them all.

College: Utah State | Height: 6-foot-2 | Weight: 202 pounds
A transfer from junior college, Austin suffered a season-ending knee injury in his redshirt junior year in 2010. He bounced back in 2011, playing in all 13 games and starting eight. As a junior, he had six touchdowns and 465 yards on 34 receptions, and in 2012 he caught five TDs and put up 729 yards on 48 receptions. At Utah State's pro day in March, Austin ran the 40-yard dash in 4.49 seconds.

College: Arkansas | Height: 6-foot-3 | Weight: 312 pounds
Bailey decided to enter the draft after his junior year, but didn't end up getting selected. From 2010 through 2012, his freshman through junior years, he started in every Razorbacks game and often switched playing left or right guard in Arkansas' system. Seattle apparently is planning to use him as an offensive tackle. Bailey earned second-team All-SEC honors in 2011, his sophomore season, and had been regarded as one of the better offensive linemen in the 2013 draft class. At the NFL Scouting Combine in February, he was one of the top performers at his position with a time of 4.95 seconds in the 40-yard dash.

College: Southern Illinois | Height: 6-foot-3 | Weight: 254 pounds
Another JC transfer, Boatright redshirted in 2010, then led the Salukis with 6.5 sacks and 13.5 tackles for loss his junior year as a starter in all 11 games. In 2012, he was a third-team All-America selection and was third on his team with 62 tackles. Boatright finished seventh in the Missouri Valley Football Conference with 5.5 sacks and led his team with 10 quarterback hurries. The Salukis' team captain posted a time of 4.77 seconds in the 40-yard dash at his school's pro day in March.

College: Miami (Fla.) | Height: 6-foot-2 | Weight: 215 pounds
Buchanan missed most of the 2012 season with an injury to his right knee -- a year after missing much of the 2011 season to another knee injury. But before that, he was an emerging star for the Hurricanes. In 2009, he played in all 13 games and started two, tallying one interception, 28 tackles and 3.5 tackles for loss. In 2010, as a starter in 10 games, he posted 54 total tackles and eight tackles for loss. Buchanan played four games in 2011 and just two last season, yet recovered in time for Miami's pro day in March. There, he ran the 40-yard dash in 4.57 seconds.

College: UNLV | Height: 5-foot-11 | Weight: 233 pounds
In 2011, his first year at UNLV after transferring from junior college, Lotulelei played in all 12 games and took over late in the season as a starter. He ranked third on the team with 60 tackles and also had three tackles for loss as a junior. Last season, as a senior, he started all 13 games and posted 120 total tackles, 1.5 tackles for loss and one forced fumble, earning him first-team All-Mountain West honors. At the NFL Scouting Combine in February, he was a top performer in his position in the vertical jump and three-cone drill, and ran the 40-yard dash in 4.84 seconds. And to answer your question: No, he is not related to defensive tackle Star Lotulelei, whom the Carolina Panthers picked 14th overall out of Utah in the NFL Draft.

College: Colorado | Height: 6-foot-0 | Weight: 219 pounds
The Buffaloes used Polk from the get-go, putting him in 10 games his freshman year, when he had 40 tackles and one tackle for loss off the bench. He became a starter in 2010 as a free safety, finishing second on the team with 72 tackles, and in 2011 started every game except the two he missed due to a concussion. Nevertheless, as a junior he posted 80 tackles, one interception and broke up six passes, plus had a 17-tackle game against Stanford. Last season, as a senior, he struggled with a severe ankle sprain that kept him out of five games and slowed him down for more, finishing with 45 tackles and two for loss in seven games. At Colorado's pro day in March, he clocked in at 4.40 seconds in the 40-yard dash.

College: Bowling Green | Height: 6-foot-4 | Weight: 307 pounds
Roussos began at Bowling Green as a defensive tackle, playing in 10 games and recording one sack and nine tackles in 10 games his freshman year. In 2010, he appeared in 10 games and switched from the defensive to offensive line for the final six games of the season, starting at right tackle. Through his junior and senior years, Roussos started every game for the Falcons and earned second-team All-MAC honors in 2012. In March, at Bowling Green's pro day, he completed the 40-yard dash in 5.39 seconds.

College: Oklahoma | Height: 5-foot-11 | Weight: 205 pounds
Whaley was a walk-on JC transfer his junior year with the Sooners and soon became their starting running back, rushing for nine touchdowns and 627 yards in seven games, including four starts. That 2011 season was cut short, however, when he suffered a serious ankle injury that tore ligaments and broke a bone. Whaley returned for six games and three starts in 2012, rushing for one TD and 243 yards as he tried to recover from his injury. At Oklahoma's pro day in March, he ran the 40-yard dash in 4.53 seconds.

College: Old Dominion | Height: 6-foot-1 | Weight: 238 pounds
Wilkins jumped feet-first into Old Dominion football as a co-captain his freshman year, starting all 11 games at free safety and finishing second on the team with 65 tackles and seven pass break-ups, plus hauling in three interceptions. In 2010, he moved to linebacker and started every game again, leading the Monarchs with 75 tackles and five fumble recoveries, adding two forced fumbles and a pick. As a junior, he led ODU again with 111 tackles and earned first-team All-Colonial Athletic Association honors, and had 3.5 sacks, two interceptions and a 17-tackle game against Hampton. Last year, as a senior, he led the team once again with 90 tackles, 6.5 sacks and three interceptions. Wilkins graduated as Old Dominion's all-time leader in tackles, tackles for loss, sacks, forced fumbles, fumbles recovered and interceptions (tied). At the Monarchs' pro day in March, he ran the 40-yard dash in 4.54 seconds and was one of the best free agents available after the draft.
